AIDS AND OUR RESPONSIBILITIES?

I think about AIDS a lot. I have no personal connection to this disease. I know no one who has it or has died from it, to the best of my knowledge. So, that's not why I care. No, generally, I am concerned about the impact AIDS has on developing societies. I am fascinated by how this modern day plague is devastating the African Continent, how social norms appear to be in the process of being rewritten as a result, how prevention and treatment are advanced and thwarted, how Asia is responding in general and india in particular, and how this might effect the world beyond the borders of those countries and continents most particularly affected. Whole generations are being more than decimated and the impact of such a reordering of population norms may not be felt for years
So what should be our resbonsibilities to avoid this?
